The Fox Report Barry Fox’s technology column Right to repair, Windows 11 and 1 Gig broadband I n the US, President Biden has signed an Executive Order which tells the Federal Trade Commission (FTC) to pass Right to Repair laws. These will force manufacturers to let individuals and independent repair companies try to fix broken equipment rather than junk and replace. The intentions are admirable, but there is a good chance of tears before bedtime as companies introduce fanciful policies. Witness the new ‘R for Repair’ tag unveiled by Dutch Philips and Chinese partner TP Vision at a recent online press conference. I tried to re-watch the live event and so be sure I had been hearing and seeing correctly. But it was gone, apparently for ever. My memory and notes are clear, though. Philips/TP Vision is now promising to let owners of TV sets do DIY repairs. Several journalists who were logged into the event, including myself, asked for more information on how Joe Public or a handyman-for-hire can get inside a modern TV set and repair faults. The answer we got from TP Vision managers was vague in the extreme. ‘Obviously people will not be able to replace components that are glued together (sic). But they will be able to do some basic things. We are on a journey. We are taking it step by step’. We asked for examples of ‘basic things’, but got none. If anyone is capable of identifying which microchip on the motherboard of a TV has gone bad, and then desoldering and replacing it with a new one obtained from who-knows-where, it is most likely to be a PE reader. Less tech-savvy owners are more likely to try hitting it with a hammer or dolloping in some WD40… inevitably finishing up with duct tape. Another fine mess Owners of Windows PCs have for many months been receiving alerts from Microsoft on Windows 11, the free upgrade to Windows 10 which (allegedly) makes a Windows PC look and feel more like a Mac. The upgrades have been staggered, by location and hardware, and who knows what other criteria, but all the PCs I have direct contact with have now been offered the chance to go up to 11. Already, there are lessons to be learned. Because the 11 upgrade offer arrives with other updates, such as security improvements, one owner clicked ‘Yes’ to 11 without realising 1551V snap-fit vented and plain miniature plastic enclosures the significance. The download then started, installed and prepared the PC for a re-start. We could find no risk-free way to undo the install. So, it duly upgraded to Windows 11. Three other machines all declined to upgrade, blaming inadequate hardware. Downloading the free software tool Health Check (which Microsoft offers via its ordinary Update option) revealed that each PC had adequate HD space and RAM, but all the CPUs were deemed inadequate even though they met the overall speed requirements. An Intel Pentium, Intel i7 and AMD A10-6700 were all deemed unworthy of Windows 11. Whole rafts of relatively recent and respected processors are also excluded. So, it is likely that many readers – and many businesses – will now find their systems rejected for upgrade to Windows 11. There are two options. Try and bypass the check by clean-installing Windows 11, or simply stay with Windows 10. Don’t force Windows 11 I’d strongly advise against trying to force an install. Although conspiracy theorists will doubtless see the chip rejection as part of some grand plan ! w ne Learn more: hammfg.com/1551v More than 5000 standard stocked enclosure designs uksales<at>hammfg.com • 01256 812812 10 Practical Electronics | April | 2022 to sell new PCs, the length of the ‘No-to-11’ list makes this highly implausible. Declined Windows 10 users are more likely to buy into the Mac world or experiment with Linux or Android Chromebooks, thereby achieving the exact opposite of what Microsoft would want. Everything points to the fact that Microsoft has blocked routine upgrades from 10 to 11 because pre-launch testing has thrown up serious crash and compatibility problems. So be very wary of trying to over-ride the block. Bugs, patches and keys Also, it is unclear whether and how a forced upgrade to 11 will receive and cope with the essential bug fixes and security patches to Windows 11 that are sure to follow. As I found out recently when a routine Windows 10 update somehow de-activated the key for a new version of Microsoft Office and replaced it with an expired key for an old trial version, juggling keys in the Windows registry requires a brave heart, strong nerve and fair knowledge of DOS Command line working; as well as self-preservation creation of registry back-ups and system restore points, in case anything goes wrong. Your starter for 10 The other, far better option is to stick with Windows 10. Microsoft has assured that support with updates will continue until October 2025. It’s likely that by then Microsoft will have patched and tweaked Windows 11 to handle many of the currently vetoed processors; and in the meantime, fixed any number of other bugs that firsttime users of Windows 11 will have suffered. Just one example: The biggest criticism of ill-fated Windows 8 was that it removed the familiar Start menu, just as Windows users had grown to ignore the absurdity of hiding the Off or Shut Down option under a Start label. A small industry grew out of third-party software such as StartIsBack that cosmetically modified the unfriendly and unfamiliar Windows 8 user interface so that it looked like the familiar and friendly Windows 7 screen. With a change of top management, Microsoft skipped Windows 9 and launched Windows 10, with the friendly, previously familiar Start menu re-instated. A colleague whose PC recently updated from 10 to 11 immediately found that the Start Option to Stop had disappeared; in desperation they Shut Down by physically pressing the ON/Off switch. Start has not actually been removed. It has just been hidden in the middle of a different-looking task bar. A few easy-when-you-know-how mouse clicks on hidden menu options will send the Start button back to where users expect it to be. A new generation of StartIsBack and similar third-party software is already available for Windows 11. What we-know-better-than-our-users mastermind inside Microsoft thought it would be a good idea to repeat the Windows 8 user alienation trick? Will an update to 11 now replace the Start button? Giga-battle We are now seeing the start of a new broadband battle, with 1 Gig FTTP (1Gbps from fibre-to-the-premises) at the heart of the sales pitch. Doubtless spurred on by new entrants to the market, like G Network in London, Virgin says it is now 1-Gig-capable across its full network (subject to availability and network Practical Electronics | April | 2022 This Windows 11-rejection message is frustrating for owners of Windows 10 (or earlier) machines, but proceed very carefully if you choose to ignore it and force an upgrade. capacity, whatever that means) – see: www.virginmedia. com/broadband/gigabit Virgin is being upfront about the elephant in room – only a few people with big houses and big needs actually need 1 Gig capacity. ‘Whether you’ve got a full house, are into serious gaming, or need to share some hefty files, 1 Gig1 Fibre Broadband has enough speed to please even the busiest of households,’ says Virgin. ‘Big family? Gig1 Fibre Broadband can power it all at the same time, without breaking a sweat. Stream Ultra HD videos while downloading mammoth files, and your kids can still FaceTime their mates. Plug in your console and game on. There’s zero traffic management, ever, so your connection won’t slow down even during peak times. Big house share? End the battle for the bandwidth. Gig1 Fibre Broadband’s got plenty of speed for everybody. You can all stream in Ultra HD, game, host Zoom calls in different rooms, download and upload university work, and more – all at the same time.’ Which, when translated, means that FTTP will be expensive overkill for Mr or Ms Average Internet user. Is it really that fast? There is another elephant in the room. Although 1 Gig may be coming into a house, speeds are likely to drop dramatically when the signal is sent round the house. Here’s what a tech savvy friend reports from his first experience with FTTP from G Network in London. Speeds ‘down’ into the home, and ‘up’ out of the home are, as is claimed, over 900 Mbps and nearly the aspirational 1 gigabit. But, and it’s a big but, this only holds good if the broadband signal is fed direct from the fibre router into a computer by a short Ethernet cable. As soon as the broadband signal is sent round the home by a Wi-Fi system, even one labelled ‘1Gb’, the real speed drops to around 400Mbps. My user friend writes: ‘Speeds of 900Mbs plus are nice and something to brag about. But I enjoyed 100Mbs previously with Virgin and that was more than fast enough for me, so (rhetorical question) who needs nearly a gigabit residentially? Since they offered me a year free as ‘the first person in the house to take up the offer’ who am I to refuse? If it all goes sideways the Virgin cabling is still in place, so reverting would be painless. Watch this space!’ 11
